Sweep with a relationship
Sweep with a relationship
(OP)
Hello Boffins
I bet someone knows the exact answer to this one.
I need to model a sweep with a relationship. I have a composite curve, which is quite complicated, and I want to sweep a circle along it with the relationship r = k * sqrt(l - 235)
Obviously the circle will have a zero radius until 235mm, so I should not start the composite curve until 235mm from the start. From here, a circle with a starting radius of 0.05mm perhaps, and then the relationship I can't get to work using trajpar.
Does the relationship need to be written in the sweep feature, i.e. sd=..., or as a part relationship, using the names of a couple of features (with trajpar_pnt)and a feature dimension d=....
Answers on a postcard please.
Many thanks
Dave

RE: Sweep with a relationship
The relation should be in the sketch.
When you are sketching the circle, hit Tools->Relations.
For the length parameter 'l', you need to multiply trajpar by the curve length. You shouldn't need to subtract 235 if you create a point first and start it from there.
Hope this helps
